i bought some infinity reference 4x6s off a buddy, and they wont fit. the bolt holes dont line up. do i have to buy a bracket or what?

 

Thats actually rather common with aftermarket 4x6's. I had a set of phoenix golds with the same problem.

Yes there are adaptor plates you can get to solve this. They can be found at pretty much and store that sells car audio.

I am sure crutchfield would have them as well.

 

is it a different mounting plate for the birds? cause mine lined up fine, same speakers...

 

either that, or get kicks, and bypass the $hitty 4x6s.

 

i have the kappas and they went in fine for me

 

Some 4x6's have a series of different holes on a larger bracket around the speaker than others.
